Blackstone Oil Analysis worthwhile??
The "how many miles on your tow vehicle" thread prompted this. I'm in the same boat as the OP of that thread, I've got 215,000 miles on a 2002 1500HD with the 6.0l gasser. It's been a great truck, b...

Personal choice and up to what you need/want out of the test
Know my vehicles very well and don't wish to spend that $28 bucks (last time checked) on a test and just apply it to synthetic oil and best filter
Now, do consider it every once in a while for older vehicles to look see how it is doing...but haven't done that on my Suburban (+168K HARD miles). Did on my old K5 and it showed no appreciable issues
Ditto hate spending money and keep my vehicles a looooong time and what they can tell on wear n tear is not as good, IMHO, as a compression test...historical listing of my dash engine oil PSI, etc
Current Suburban 7.4L at 168K miles...dash oil PSI gauge says 75PSI on freeway, fully warmed up. Back a few years ago it was over 80PSI warmed highway (1,000 RPMs and up) and pegged when cold. Idle was 45PSI warm and 50 or so PSI cold...now down to 40PSI warmed and 45PSI cold. Synthetic (Mobil) 15-30 and even 0-30 but don't like any zero viscosity for my vehicles
Just my opinion on this matter
